As concerns the timing of administration and doses of medications, phase I/II studies are ongoing with R-CHOP in combination with Revlimid (Lenalidomide) in DLBCL. The latest presentation is by Nowakowski et al. at ASCO meeting in June 2010. This study determined the maximum tolerated dose of Revlimid(Lenalidomide)administered on days 1-10 with standard R-CHOP (R2-CHOP). NO DLT was found and 25 mg of Revlimid(Lenalidomide)was the recommended dose for phase II with enrollment of 32 patients. These encouraging results permit to introduce in our much less toxic protocol 25 mg of Revlimid(Lenalidomide)as initial dose, with progressive reduction in case of toxicity.
